You say ML Motif is 0.52 ohms at 20kHz and your measurements imply the amplifier's output impedance is 2.5 ohms on the 8 ohm tap.

If we assume the Motif might have a 16 ohm impedance peak somewhere in its pass band (a reasonable assumption) then the voltage at the Motif will vary by 14dB between that impedance peak and the 0.52 ohms at 20kHz.

14dB.....now that's a recipe for changing the sound of the Motif :)

You reviewed this amplifier with 3 powered woofer speakers. How can this describe anything about the amplifiers ability to produce bass or handle a full frequency speaker load? Also I am not the least bit interested in your comments regarding it's sound quality as compared to those other very expensive components. What good is that to someone (me) interested in this amp? Compare it to like priced units that the reader most likely will be considering. I'm 61 YO and have been reading stereophile & tas for all of my adult life. At least 80% of your reviews, not just yourself, are of dubious merit.
